De Exif Orientation Tag

Enig idee waar ik het over heb als ik zeg "Exif Orientation Tag"? Juist ja, dat is het stukje metadata in de jpegs van je camera waar wordt opgeslagen hoe de foto is genomen. Er zijn in totaal acht vormen van orientation waarvan de populairste "top left side" (portrait) en "right side top" (landscape).

Windows XP heeft er standaard geen ondersteuning voor, foto's worden niet automatisch gedraaid. Google Picasa blijkt er wel standaard ondersteuning voor te hebben. Dat was ook voor mij de aanleiding om op zoek te gaan hoe mijn camera dit zinvolle gegeven door weet te geven aan Picasa. Juist, via de Exif Orientation Tag! Zie ook de volledige Exif specificatie.

Exploring advanced DOM interop with Blazor WebAssembly

Afbeelding
With the establishment of WebAssembly in the browser space, JavaScript is not the only option anymore to run code in the browser. You can start building your modern web applications in any language of choice. Recently Microsoft has released the first version of Blazor WebAssembly. It enables you as a .NET developer to run .NET code through WebAssembly. Blazor also comes with a websocket based server model. You can check out Blazor on Microsoft Docs: https://docs.microsoft.com/en-us/aspnet/core/blazor I have been building a couple of Blazor experiments myself, of which the following two stand out: Real-time Blazor server web app. I have added a second SignalR hub to this app in order to communicate signals from one Blazor session to another.

If I find time I will blog about all my adventures to getting this deep zoom Mandelbrot to work! Try it online It was the latt...

Extend Azure DevOps with Azure Functions

With Azure DevOps, Microsoft provides a rich platform for building your continuous integration and continuous delivery (CI/CD) workflows. Refer to https://azure.microsoft.com/en-us/services/devops/ Our CI/CD design Lately we came up with the following CI/CD design: Notice the following features: When a feature branch is created, an app service slot is created and the feature workload is deployed to this slot; When a feature is merged with master, the slot gets removed and the master workload gets deployed to the production slot. Learn more about Azure App Services and its deployment slot feature here: https://docs.microsoft.com/en-us/azure/app-service/deploy-staging-slots Implementation In order to learn how to set up the above workflow you can read the following excellent blog post of Lucas Caljé: https://levelup.gitconnected.com/manage-appservice-slots-with-azure-yaml-pipelines-3fb2a2e5da9a Interestingly, Lucas' solution does not require any external integratio...

Azure Custom Role Definitions and Assignment Scopes

Afbeelding
Working with custom Role Definitions in Azure can be a funny thing. Interestingly, when reviewing the Azure Active Directory user interface in Azure Portal you will not find a way to query all available role definitions. If you query the Roles and Administrators view you will only see administrator roles: With a PowerShell cmdlet you are able to list all. Get-AzRoleDefinition | select name | sort name | ft results in something like the following: Name ---- AcrDelete AcrImageSigner AcrPull AcrPush AcrQuarantineReader AcrQuarantineWriter API Management Service Contributor API Management Service Operator Role API Management Service Reader Role App Configuration Data Owner ... But are these really all the role definitions out there? Obviously not! This list is scoped to the subscription you are currently targeting with your current Azure Context. In order for you to try out yourself, just create a couple of role definitions with various assignment scopes. Assuming you have owne...
